The Michigan College of Mining and Technology's Department of Mineral Dressing offered courses for students intending to enter the field of mineral beneficiation, which studies methods used in the separation and preparation of metals and non-metals for further treatment or final use. It was listed as a separate department in the university course catalog until 1960, when it was designated as a specialization within the Department of Metallurgical Engineering.
